What TennMax America does

TennMax America, Inc. is a privately held specialty industrial manufacturer founded in 2004 and headquartered in Vancouver, Washington, that designs and produces electromagnetic interference (EMI) shielding and thermal management materials and sub-assemblies for enterprise, defense, and aerospace OEMs. Its core product portfolio spans seven technology platforms: Physical Vapor Deposition (PVD) metallization for cost-effective shielding of plastic housings; Form-In-Place (FIP) four-axis automated dispensing of conductive elastomer gaskets; thermal interface materials (gap filler pads and dispensable silicone and non-silicone jellies); simulation-driven custom thermal modules integrating heat sinks, embedded heat pipes, and water cooling cold plates; turnkey end-to-end enclosure solutions that combine metal housing, EMI gasket, thermal module, and thermal interface materials into a single qualified functional gasket; and RF and microwave absorbers. Manufacturing is executed through wholly-owned subsidiaries in Taiwan (TennVac Technology Co., Ltd.) and mainland China (TennVac Shenzhen, TennMax Electronic Material Kunshan, TennVac Zhongshan), giving the company eight global offices and factories that together enable 24/7 engineering support, rapid prototyping, and last-mile logistics for enterprise customers.

The company sells under a B2B enterprise field-sales motion with custom, quote-based pricing and multi-year contract cadences, engaging customers through direct technical inquiries, custom design collaboration in early-stage product development, and a structured brand portal for existing accounts. Its customer base is bifurcated between enterprise electronics and aerospace/defense manufacturers subject to ITAR controls and a secondary consumer electronics segment. TennMax's go-to-market relies on its company website (product pages, technical selection guides for FIP, TIM, and absorbers, and articles), direct inquiry forms with lead-source attribution, LinkedIn presence, and industry events. The firm does not publish standard pricing tiers; all engagements route through direct sales and engineering contact.

TennMax holds ISO 9001, AS 9100 aerospace quality certification, ITAR registration with the U.S. Department of State, and Cybersecurity Maturity Model Certification (CMMC) / NIST SP 800-171 compliance, positioning it as a qualified supplier for defense primes and government programs. The legal entity is TennMax America, Inc., a U.S. corporation domiciled in Vancouver, WA, with no public listing, no disclosed funding rounds, no disclosed acquisitions, and no parent company. Revenue, headcount beyond the 11-50 U.S. employee band, and management team details are not publicly disclosed.
